Many chemical structure questions can be answered with 1H-1H distance estimates derived from the 1D NOESY experiment. There are a variety of ways to set up this experiment, but we now have two short videos that UChicago users can access with their phones at the spectrometer – no homework or special prep required.

Tweaks have been made to all default 1H and 13C 1D and 2D experiment parameter sets so they have been tested as effective and are the same on all spectrometers. If you have a 10mg properly-prepared sample, you are assured of getting good data using default parameters with these experiments no matter which instrument you use.

500-1 is open, supporting walkup experiments in Searle. It’s outfitted with a different probe to provide better 13C sensitivity and capabilities of observing 31P, 11B, 195Pt, and more. Spectra are shown for a standard 10 mg/mL sample of carvone to provide a visual basis for comparison.
